Diamond wheel structure generally consists of working layer, substrate, transition layer composed of three parts.

Working layer, also known as the diamond layer, composed of abrasive, bonding agent and filler, is the working part of the wheel. Transition layer, also known as non-diamond layer, by the binding agent, metal powder and filler, the diamond layer is firmly connected to the substrate on the part.

The base is used to receive the abrasive layer and is securely clamped to the grinder spindle with a flange during use. General metal binder products use steel, alloy steel as matrix; resin binder selection of aluminum alloy, Bakelite as the matrix. Manufactured from aluminum, steel or Bakelite, supporting the working layer and retaining chuck. Wheel forming quality is good or bad and the use of high and low precision has a great relationship with the substrate.
